SOTA.

ToaZZ 107mm t may concern Be it known that I, VVAr/rnn OLsEN, aV

citizen of the United States, residing at Albert Lea, in the county of Freeborn and State of Minnesota, have invented certain new and useful Improvements in Collapsible Ovens and Carrying Cases; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates toa device which is designed to be used as an oven to b'e placed on a small stove such as is often used in camp- 'ing outts. The device is also`constructed so that it may be collapsed into a small space and when so collapsed can be used as acarrying cabinet, in which a small stove or any other desired articles may be packedl and carried.

It is an object of this invention to provide such a device having a small number of parts, which parts are designed to be folded int-o a very small space'.

Y This and other objects and advantages of the invention will become apparent from the following description made in connection with the accompanying drawings in which like reference characters refer to the same partsthroughout the different views and in whichi y Fig. 1 is a cent-ral longitudinal section of the device showing the same arranged as an oven;

Fig. 2 thereof; Y y Y YF ig. 3 isa transverse central section of the device showing the same collapsed for is a transverse central section use as a carrying case; and 40I Fig. t isa longitudinal central section of the coverV or lidfor the device.

Referring. to the drawings The device comprises a member l which.

. is formed asa rectangular boxl open at its upper end. This member is preferably made of thin sheet metal and the'expo'sed edges thereofwill be suitably relieved of sharp portions.` As stated, the device' is open at itsupper end and' has an. opening 2 cut in its kbottoni .portionleavingthe' outstanding flange 3 surrounding said opening.. A. frame memberdesignated generally as a is arranged to co-operate and be supported` bythe member l. The member t comprises .a grid formed with longitudinalspacedrod Specification of Letters Patent.

members 4 which are connected at their end portions by transverse rod members 5 shown asfdisposed thereabove. A fiat piece ofmetal 6 has its lower edge kbent around the outer rod land is formed at its upper edge with an outturned Ubend which as shown in F ig. 2 is adapted to engage with the' upper side edge of the member 1. The outer edge of the member 6 is again turned upwardly a short distance to form a longitudinally extending trough (3a which will be disposed outside of the member l. It will be understood'that there is a member 6 at each side of the frame member a. vRod members 7 have their upperen'ds formed as rings or loopsk and enclosingY certain of the rods 4, which as shown in Fig. 2 are the ones adjac'entto the outermost rods. The rods 7 have their intermediate portions depending and extending longitudinally under Vthe said rods 4; and a plate ymember 8 has its side edges bent around the member 7 and is supported by and extends betweenthe same, being thus 'supported at some distanceV below the grid member. v y

The casing member 9 which also comprises a rectangular box member havingY one side open is provided to form the top or cover 'for themember l. vMember 9 is also preferably vformed ot thin sheet metal and will also preferably have its exposed edges suitably relieved. of sharp portions. The dimensions of the member 9 are such that it can be placed over the member 1 as shown in F io. 2 and its side edges will restvin the trough member 6a while its end edges will extend along outside of the end edges of member 1 asl shown in Fig. 1. The member 1 is provided at one side 'substantially-cen` be collapsed into 4substantially the Y form shown in Fig. 3. When the members 7 are folded dovs'rnwardly onto the plate 8 and the members are' Ylikewise folded downwardly into contact with the rods et, the frame a as so folded is disposed in the bottom of member 1 and said the n i'einber 9.

member then -placed in A convenient member 13 is provided which is falso formed as a shallow rectangular boX with apertures 14151.` It will', of course, beV

understood that the exposed edges of the members 13 and 14 can be suitably beaded or inturned so that the same will not be objectionably sharp oi' rough.

When the device is disposed Figs. 1 and 2, it forms a simple and convenient oven or cooking chamber adapted for use with a small stove of any type,

or the same can be placed between stones or brackets overa fire. The pans or cooking receptacles will be placedon the grid formed v .by members t and 5 and theplate 8 Will constitute aV heat delecting or radiating plate. When the device is so used as an oven, the member 14C can be swungY open 1n respect to the'lid 13 and these members can then be placed aboutthe stove or fire to form a suitable Wind shield therefor.` ,It vvillvthusbe seen that the device forms a compact, simpley -and eiiicient'oven or cooking chamber.

When it isdesired to transport the device, the same Will'be collapsed as shown inFig.

' '3 With 'the casing 1 disposed in themember 9. TheV lid 13 Will then be placed on the member 9 as shown vin said figure and the' holes 14a in the lid Will engage. over the pins 12, Y this` engagement being made possible bythe resiliencyof the metal. To engage or disengage the pins 12, theends of the niem- 4 ber 9 are pressed slightly inwardly vand feo.

' carrying. case,

When relieved Will spring' outv and Whenthe pins are thus located in the apertures 14a there will be no tendency for theasame to be disengaged. lVith the lid in position, the device is now converted into a rectangular which can be liftedy and carried by the handle 10. The device vis Idesigned particularly to convenientlyV receive and carry the collapsed camp stove described.V

andclaimed in the pending application S. N. 181,938, andV July 21, 1917, by Hansv o. Hanson. It' will, of course, be obvious that any desired articles may be placed in the carrying case and transported.

rom the above .description it ivill be seen that applicant has produced a simple and eficient device and one which will have great utility for the purpose intended. The' same can be cheaply made, The parts ofthe device are so constructed that there is nothing to become disarranged or get out of order Vand can be quickly set up as an oven or disassembledasla carrying case. In practice, the casing parts 1, 9,13 and 14 will preferably be painted or coated with suitable noncoirosive material. l

It will, of course, be understoodthat various changes may be made in the form, details and proportions of the parts Without departing from the scope of applicants in-y vention, which generally stated Yconsists in the matter shovvnand described ,and set forth' Y in the appended claims. v
